BACKGROUND OF THE INVENTION

Napkin dispensers are well known in the art. Typical napkin dispensers include a housing and a storage magazine for receiving a stack of napkins. A metering device may also be included in the napkin dispenser to monitor when the dispenser requires refilling. The metering device may include other mechanical mechanisms to enhance the determination of when the dispenser requires refilling. Napkin dispenser may also include the use of spring biased leaves or biased spring elements for convenient extraction of the napkins. A disadvantage of known napkin dispensers includes the need for mechanisms to advance napkins in the dispenser and signal a need to refill the dispenser. Another disadvantage of known dispensers is the cost of manufacturing and maintaining the dispensers.

DETAILED DESCRIPTION OF THE INVENTION

An exemplary embodiment of a napkin stack 10 according to the present invention is shown in FIG. 1 and includes a plurality of napkins 14 each having edges 18. The napkins 14 may be made of a suitable material, for example, paper. In the napkin stack 10 each napkin 14 has four edges 18. As can be seen in FIG. 1, a plurality of adhesive elements embodied as glue tabs 20 are positioned adjacent corners of the napkins 14. The glue tabs 20 are orderless and non-toxic, and may be an edible adhesive glue. Further, for example, the adhesive elements could be a touch fastener such as VELCRO®, or a tape, or another adhesive element in keeping with the spirit of the invention. Additionally, the adhesive elements may also include a layer of adhesive (which may be sprayed or otherwise applied to the napkin) possibly adjacent the napkin edge. It is understood that the adhesive elements 20 may be positioned along the edges of the napkins, in a pattern, or in any manner achieving the function of removable affixing the napkins in the stack 10. In FIG. 1, the glue tabs 20 are positioned on the top of each napkin 14, however, the glue tabs 20 may also be positioned on the bottom of each napkin, or on both sides of the napkin. The glue tabs 20 may also be positioned in mating relation with each other. Further, the glue tabs 20 are shown in the same location on each napkin 14 but may also be in different location or in a random pattern.

The glue tabs 20 removable attach each napkin 18 to the napkin on top of it to provide a napkin stack 10 as shown in FIG. 1, where the edges 18 of the napkins 14 are equidistant from the longitudinal axis 30. Thus, a single napkin 14 or a selected amount of napkins may be removed from the napkin stack 10. Each napkin 14 is one layer, however, the napkins may also be multiple layers, and in the same manner as shown in FIG. 1., be stacked and removable. A multiple layer or ply napkin (not shown) may have glue tabs 20 on each layer, or on a top or bottom layer leaving inner plies without glue tabs 20.

In another embodiment according to the present invention, as shown in FIG. 2, a napkin stack 100 includes a plurality of folded napkins 104 each having edges 108. It is understood that the napkins may also be shaped triangularly without folding or in a plurality of other shapes (not shown). In the embodiment shown in FIG. 2, the triangularly folded napkins 104 are substantially equidistant from a longitudinal axis 110 to form the uniform napkin stack 100.

Similar to the napkin stack 10 embodiment shown in FIG. 1, the glue tabs 20 removable attach each napkin 104 to the napkin on top of it as shown in FIG. 2. Thus, a single napkin 104 or a selected amount of napkins may be removed from the napkin stack 100. As can be seen in FIG. 2, a plurality of adhesive elements embodied as glue tabs 20 are positioned adjacent comers of the napkins 104 similarly to napkins 14 show in FIG. 1. The adhesive elements 20 may be positioned along the edges of the napkins 104, in a pattern, or in any manner achieving the function of removably affixing the napkins in the stack 100. Similar to the napkin stack shown in FIG. 1, the glue tabs 20 shown in FIG. 2 are positioned on the top of each napkin 104, however, the glue tabs 20 may also be positioned on the bottom of each napkin, or on both sides of the napkin, or in different location or in a random pattern.

A method for stacking napkins according to the present invention includes providing a plurality of napkins as shown in FIG. 1, wherein a plurality of glue tabs 20 are at specified locations adjacent edges 18 of each napkin. The napkins are then stacked in any number desired to form the napkin stack 10 where the napkins 14 are removably affixed to each other by the glue tabs 20. A person may then remove one or more of the napkins 14 by peeling away the desired number of napkins 14. One advantage of the present invention is that it eliminates the need for a napkin dispenser. The napkins 14 or 104 according to the present invention maintain their uniform appearance and are not blown by the wind or accidentally knocked asunder. Once the napkins are dispersed from the stack and on a floor or table they can be unsanitary for use and at least lose their orderly appearance. Thus, the napkin stack of the present invention remedies these problems by providing a removably attached napkin stack.

The napkin stacks 10, 100 shown in FIGS. 1 and 2 may also be provided as a kit comprising a plurality of napkins, and a plurality of adhesive elements such as glue tabs that can be added at specified locations adjacent the edges of each napkin. The plurality of napkins are thereby removably affixed to each other to form a stack in a specified pattern as shown in FIGS. 1 and 2.

The napkin stack according to the present invention does not require a dispenser to maintain a uniform stack. This provides a major advantage and cost savings over known devices and methods of uniformly stacking and making napkins available.
